Digital document update

Abstract

Techniques and systems are described in which a document management system is configured to update content of document portions of digital documents. In one example, an update to the digital document is initially triggered by a document management system by detecting a triggering change applied to an initial portion of the digital document. The document management system, in response to the triggering change, then determines whether trailing changes are to be made to other document portions, such as to other document portions in the same digital document or another digital document. To do so, triggering and trailing change representations are generated and compared to determine similarity of candidate document portions with an initial document portion.

What is claimed is:

 generating, by the computing device, a plurality of candidate trailing change representations from respective ones of a plurality of candidate document portions; 
 generating, by the computing device, a plurality of similarity scores by comparing the triggering change representation to the respective ones of the plurality of candidate trailing change representations; 
 ranking, by the computing device, the plurality of similarity scores; and 
 outputting, by the computing device, the ranked plurality of similarity scores to control application of trailing changes to respective ones of the plurality of candidate document portions that are based on the triggering change to the initial document portion. 
 
     
     
       2. The method as described in  claim 1 , wherein the generating of the triggering change representation is based on the initial document portion before the triggering change is applied.
